CDP does not update records in the Silverpop contact databases, we push the audiences and content to Relational Tables.
IBM Watson campaign automation has some limitations in terms of the maximum number of relational tables, of rows across relational tables, etc… For instance: they support only 10M rows across all RT in one account, and they support 10 RT at most per account. You should check with your IBM account manager regarding your current capacity.
